Tags ICC profiles in images only not text or vector objects , which prevents black text from undergoing any color shift when distilling Acrobat 4. Calibrates color, making it device-independent. Recommended for PDFs that will be used onscreen or with low-resolution printers. All Working Spaces must be specified. Document Rendering Intent. Choose a method to map colors between color spaces. The result of any particular method depends on the profiles of the color spaces. For example, some profiles produce identical results with different methods.

Acrobat also includes a rendering intent called Preserve, which indicates that the intent is specified in the output device rather than in the PDF. In many output devices, Relative Colorimetric is the default intent. In all cases, intents may be ignored or overridden by color management operations that occur subsequent to the creation of the PDF file.

Working Spaces. Choose a profile to define the color space of all grayscale images in files. Choose None to prevent grayscale images from being converted.

Choose a profile to define the color space of all RGB images in files. Choose None to prevent RGB images from being converted. Choose a profile to define the color space of all CMYK images in files. The default is U. Choosing None for all three working spaces has the same effect as selecting the option Leave Color Unchanged. Retains these settings if they exist in the PostScript file.

Black generation calculates the amount of black to use when reproducing a color. Undercolor removal UCR reduces cyan, magenta, and yellow to compensate for black generation. When Transfer Functions Are Found. Specifies how to handle transfer functions in PDFs. Transfer functions are used for artistic effect and to correct for the characteristics of a specific output device.

Deletes any applied transfer functions. Applied transfer functions should be removed, unless the PDF is to be output to the same device that the source PostScript file was created for.

Retains the transfer functions traditionally used to compensate for dot gain or dot loss that may occur when an image is transferred to film. Dot gain or loss occurs when the ink dots that make up a printed image are larger or smaller than in the halftone screen.

This method is useful for creating color effects in a file. Preserve Halftone Information. Retains any halftone information in files. Halftone information is intended for use with a particular output device. In a PostScript file, DSC comments contain information about the file such as the originating application, the creation date, and the page orientation and provide structure for page descriptions in the file such as beginning and ending statements for a prologue section.

DSC comments can be useful when your document is going to print or press. Allow PostScript XObjects. Use only in controlled workflows where there is no other option. Convert Gradients To Smooth Shades. Converts blends to smooth shades for Acrobat 4. Convert Smooth Lines To Curves. Reduces the amount of control points used to build curves in CAD drawings, which results in smaller PDFs and faster onscreen rendering. Preserve Level 2 Copypage Semantics.

If you have a PostScript file and select this option, a copypage operator copies the page. If this option is not selected, the equivalent of a showpage operation is executed, except that the graphics state is not reinitialized. Preserve Overprint Settings. Retains any overprint settings in files being converted to PDF. Overprint settings create color by printing one ink on top of another ink.

Overprinting Default Is Nonzero Overprinting. Embeds the settings file. When deselected, performance improves because only decompression, not recompression, occurs.

Job tickets describe the PostScript file and can be used later in a workflow or for printing the PDF. Use Prologue. Sends a prologue and epilogue file with each job. These files can be used to add custom PostScript code that you want to have executed at the beginning or end of every PostScript job being converted.

Sample Prologue. Or, you can type the path into the Address text box. In Acrobat Standard, Distiller processes prologue and epilogue files only if both files are present and located properly. The two files must be used together. In Acrobat Pro, Distiller processes prologue and epilogue files only if both files are present and located properly.

If the prologue and epilogue files are at the same level as the In and Out folders of a watched folder, they are used instead of the ones in the Distiller folder. Process DSC Comments. Log DSC Warnings. Displays warning messages about problematic DSC comments during processing and adds them to a log file. Preserve OPI Comments.

For more information, see the OPI 2. Print a color composite Acrobat Pro. Specify page handling options. Click Advanced, and select Output on the left side of the dialog box. Choose a composite option from the Color menu.

Specify other color and output settings, and click OK. If the document contains objects with transparency settings, select an option from the Transparency Flattening Preset menu. About separations Acrobat Pro. Print color separations Acrobat Pro. Prepare to print separations. Before you print separations, do the following:. Calibrate your monitor.

See Calibrate and profile your monitor. Specify whether the document contains trapping information, if known. See Declare the presence of trapping information. Protect PDFs. PDF Forms. Sign and Send PDFs. Print Production. PDF Standards. Acrobat DC.

Acrobat XI. Acrobat X. Acrobat 9. Acrobat Reader. View transcript. For the Matching Criteria, pick an option from the Object Type drop-down or leave the default Any Object to convert the entire page to grayscale.

In the Conversion Attributes, choose Gray Gamma 2. Click OK and review the warning message. If converted, Acrobat uses the device-independent object information. Objects set in spot colors can be preserved, converted, or mapped aliased to any other ink present in the document. Spot colors mapped to other inks can be previewed in the Output Preview dialog box. If you want to convert specific spot plates, use Ink Manager in combination with the Convert Colors tool.

To convert only specific spot plates to process, map them to process in Ink Manager. Otherwise, all spots in the document are converted to process if you have selected Spot Color as the color type. In the Convert Colors dialog box, select a conversion command. If the list contains no existing commands, click Add to add the default conversion command. Specifies if you want to convert the colors for all objects or for a specific type of object within the document. Convert To Profile.

Uses the destination space profile to convert color objects to a common ICC profile for an output device. Select Embed to embed the profile. Selecting Embed tags all objects with the selected conversion profile. In this case, you can embed a separate color profile to calibrate the color for each color space, for a total of three profiles. Preserve Black. When transforming colors to prepare CMYK documents for a different target print profile, preserves primaries.

For colors with just one colorant, Acrobat uses that colorant. For colors with more than one colorant, Acrobat finds the color with the smallest color difference. Click Document Colors to see a list of color spaces and spot colors in your document.

To create a preset based on your settings, click Save Commands. You can later import the settings by clicking Load Commands. The Edit Object tool can change the color space of selected objects.

In the Discard Objects area, you can select from these and other options:. Disables all actions related to submitting or importing form data, and resets form fields. This option retains form objects to which actions are linked. Flatten Form Fields. Makes form fields unusable with no change to their appearance. Form data is merged with the page to become page content. Discard All JavaScript Actions. Discard All Alternate Images.

Removes all versions of an image except the one destined for on-screen viewing. Some PDFs include multiple versions of the same image for different purposes, such as low-resolution on-screen viewing and high-resolution printing. Discard Embedded Page Thumbnails. Removes embedded page thumbnails. This is useful for large documents, which can take a long time to draw page thumbnails after you click the Page Thumbnails button.

Discard Document Tags. Removes tags from the document, which also removes the accessibility and reflow capabilities for the text. Convert Smooth Lines To Curves. Reduces the number of control points used to build curves in CAD drawings, which result in smaller PDF files and faster on-screen rendering.

Detect And Merge Image Fragments. Looks for images or masks that are fragmented into thin slices and tries to merge the slices into a single image or mask. Discard Embedded Print Settings. Discard Embedded Search Index.

Discard Bookmarks. Removes information in the document information dictionary and all metadata streams. Removes all file attachments, including attachments added to the PDF as comments. Removes links to other documents.
